The times required for encoding, mental rotation, and comparison of unfamiliar stimuli
(patterns of filled-in squares in a 3× 3 matrix) were found to increase with stimulus …

The original studies of mental rotation estimated rates of imagining rotations that were much
slower when two simultaneously portrayed three-dimensional shapes were to be compared …

Two experiments are reported in which Ss were required to determine whether a random,
angular form, presented at any of a number of picture-plane orientations, was a “standard” or …

Abstract Subjects from Grades 3, 4, 6, and college judged whether pairs of stimuli were
identical or mirror-image reversals. One stimulus of a pair was presented upright; the other …

Both spatial and propositional theories of imagery predict that the rate at which mental
images can be rotated is slower the more complex the stimulus. Four experiments (three …

Subjects imagined a designated two-dimensional shape rotating within a blank, circular field
at a self-determined rate. At some point during the mental rotation, a test shape was …

Abstract 9-, 13-, and 20-year-olds were tested on 3840 trials of a mental rotation task in
which they judged if pairs of stimuli presented in different orientations were identical or …

Diverses considérations empiriques et théoriques laissent supposer qu'il doit être plus
difficile de faire mentalement la rotation d'objets tridimensionnels que celle d'objets …

Abstract We tested 11-and 20-year-olds on 3360 trials of a mental rotation task in which they
judged if stimuli presented in different orientations were letters or mirror images of letters …

The 3D cube figures used by Shepard and Metzler [Shepard, RN, & Metzler, J.(1971).
Mental rotation of three-dimensional objects. Science, 171, 701–703] have been applied in …
